Privacy Policy - Dehweles

1) Who we are

Dehweles: Route Recovery is developed and provided by Saifullah Ahad ("we", "us", "our"). Developer portfolio: https://saifullah.ai.

2) Overview and Promise

Dehweles is an offline-first route comparison and recovery verification tool for passenger car drivers. It evaluates routes based on whether an exclusion-respecting return path exists if a turn is missed. We respect your privacy completely. We do not track you, sell your data, display advertisements, or upload your private locations.

3) Permissions and Data Handling

• Location (ACCESS_FINE_LOCATION, ACCESS_COARSE_LOCATION): Used exclusively on your device to match your current vehicle position to the planned road graph during active guidance. Location coordinates are processed in memory with a sliding 30-second window and are never written to disk or transmitted to any server. Location permission is optional; route planning, inspection, and comparison work 100% offline without location access.
• Foreground Service (FOREGROUND_SERVICE_LOCATION): Used solely to maintain turn-by-turn navigation updates when the screen is locked or while another app is visible during an active trip. Starts only after an explicit "Start Guidance" action and terminates immediately upon stopping.
• Network (INTERNET, ACCESS_NETWORK_STATE): Used solely to download signed public regional map pack files when explicitly requested by you. No route endpoints, travel history, or user identifiers are sent during map pack downloads.
• Notifications (POST_NOTIFICATIONS): Used on Android 13+ to display the next navigation maneuver and provide a persistent "Stop" control in the notification drawer.

4) On-Device Encrypted Storage

Saved plans and recent trip drafts are stored locally on your device within an encrypted Room database using AES-256-GCM authenticated encryption. Cryptographic keys are managed securely by the Android Keystore system. Unsaved drafts automatically expire after 7 days.

5) Third Parties and Analytics

Dehweles contains zero third-party analytics SDKs, zero advertising networks, zero tracking trackers, and zero cloud synchronization. We do not share, sell, or monetize any user data.

6) Data Retention and Deletion

All private routing data remains exclusively on your device. You can delete individual saved plans, downloaded map packs, or clear all app data at any time from within the app settings or via Android system settings.

7) Children's Privacy

Dehweles is a general navigation utility designed for licensed passenger car drivers and is not directed at children under the age of 13. We do not collect personal information from any user.

8) Changes to This Policy

Any updates to this Privacy Policy will be published at https://privacy.saifullah.ai/dehweles.html with an updated effective date.
